SPECIFICATION forming part of Letters Patent No. 767,487, dated August16, 1904. Application filed December 19, 1903. Serial No. 185,867. (Nomodel.)

To all whmn it may concern:

Be it known that I, VV'ILLIAM E. MONROE, a citizen of the United States,residing at Newport, in the county of Campbell and State of Kentucky,have invented certain new and useful Improvements in Screens, of whichthe following is a specification.

My invention relates to screenssuch as window-screens, door-screens, andthe like and has for its object the providing of a screen ofthecharacter mentioned of simple and durable construction which is capableof being readily assembled and taken apart for the purpose of renewingthe screen-cloth therein, and I 5 the invention will be readilyunderstood from the following description and claims and from thedrawings, in which Figure 1 is a perspective view of my improved deviceshown in assembled form in connection with a window frame partly brokenaway, the screen cloth being also shown partly broken away. Fig. 2 is aperspective view showing the several frame-sections of my improveddevice in dismantled form, but correlated in approximate position forassembling one corner thereof. Fig. 3 is a perspective view of thecorner-brace of my improved device. Fig. 4: is a perspective viewshowing one corner of my improved device, 0 the frame-sections beingshown in assembled form and showing a fine-mesh screen at one side and acoarse or protecting mesh screen at the other side thereof, the severalcorners of my improved device being duplicates of each other. Fig. 5 isa cross-section showing the walls of the inner frame-sections flexedoutwardly for receiving the screen-cloth, a finemesh screen-cloth beingshown as received upon one side and acoarse or protecting meshscreen-cloth being shown as received upon the other side of theframe-sections. Fig. 6 is a cross-section of the same, but showing thewalls refleXed to normal position and the outer frame-sectionstelescoped to innermost position about the inner frame-sections andcloths in full lines and also showing the outer framesections in dottedlines in assumed position for adjusting the size of the screen. Fig. 7is a perspective view, partly broken away, of

a portion of the runway of my improved device. Fig. 8 is a perspectiveview showing one corner of my. improved device in assembled form andhaving the outer corner-section taking over the corner thereof. Fig. 9is a perspective view of the said outer cornersec-, 5 5 tion.

A is an inner corner-section, of which there is preferably one at eachcorner.

B is the corner-brace of the inner corner section and has an aperture 6at its angle and ()0 wings b 6 From the respective wings a channeled orU-shaped stile-section C and a channeled or U-shaped rail-sectionDprojects, forming, respectively, part of the rail and stilethat is, ofthe side and the bottom or 5 top of the inner frame of the screen-thestilesection and rail-section being secured to the corner-brace byhaving flanges thereon taking over said corner-brace and having teats Fstruck out from the U-shaped pieces and tak- 7o ing over thecorner-brace. A spanner-section E connects the corner-sections foraiding in forming the stile or rail of the inner frame, thespanner-section telescoping with the corner-sections for aflordingadjustability in width or height of the frame. The spannersect-ion ispreferably U-shaped, the walls 6 e of which have flanges c at theirouter edges turned inwardly, the walls a a of the cornersections takinginto the spanner-section, the extreme end corners of the walls being cutaway, as shown at (0 for permitting the corner-sections to be readilyinserted into the spanner-sections. This construction permits the sameinner corner-sections to be used for 5 a wide range in sizes of screens.

F F are screen-cloths, either one or both of which are adapted to beplaced over the inner frame, outer channeled or U-shaped sections G,having walls g g, taking over the cloth 9 and walls of the inner framefor holding the cloth in place. In Figs. 4;, 5, and 6 the cloth F isshown as of flne or fly-screen mesh, placed upon one side of the frame,while the cloth F, is a heavier cloth of coarse or protecting meshplaced upon the other side of the frame.

My improved device provides means whereby two screen-cloths of differentmesh, sepa- .rated a distance corresponding to the thickness of theinner frame, may be releasably secured to the same frame, and alsopermits screen-cloth to be placed on either side of the frame.

In placing the cloth upon the inner frame the outer edge f of the clothis bent over the wall and turned into the channel of the innerframe-sections, the wall at one or both ends of the inner frame havingbeen slightly bent or flexed outwardly, as shown in Fig. 5, preparatoryto having the outer channel-sections placed thereover, as shown in Fig.6. As will be noticed from Fig. 5, when the outer edge of the wall ofthe inner frame is bent or flexed outwardly it swings that edge into avertical plane nearer the vertical plane of the middle of the frame, andthe cloth being placed over the edge so flexed, when the edge isreflexed to normal position, the cloth will be stretched.

The outer frame-sections G take over the inner frame-section and thescreen-cloth which has been placed thereon, thereby locking the cloth inposition, the said outer channel-sections also compelling theoutwardly-bent walls of the inner channel-sections to resume theirnormal position, thereby stretching the cloth upon the frame. In theform shown the outer channel-sections forming the outer stiles take overthe outer channel-sections forming the outer rails at the corners of thescreen, the outer stiles being provided with slots g at each end, theouter rails being preferably provided with slots 9, bolts taking throughsaid slots and the apertures Z, which apertures 7) give clearance forthe belts, with nuts screwing over the bolts, thus completing an outerchannel-frame having an inner channel which takes over the innerchannel-frame having an outer channel, already described. My improvedconstruction provides a metallic screen having a box-like frameadjustable in width. The slots g either or both, are for the purpose ofpermitting final adjustment in width or height of the frame foraccommodating various sizes of window-frames, transoms, or the like forwhich the screen may be intended, it being only necessary to slip theouter channel-pieces laterally to exactly fit the screen to its intendedlocation, the outer channel sections being preferably of approximately alength for the finished frame.

H is an outer corner-section. This outer corner-section is preferablystruck from one piece of metal and consists of walls ]L h, connected bya web b the walls being each provided with a flange it", the flangeswhen the corner pieces are in position substantially meeting at theiredges. A nut-and-bolt connection Z2." takes through apertures in thewalls of the outer corner-section, screwing the parts rigidly in place.The outer corner-section also, preferably, has flanges 71. if at itsinner diagonal edges. The outer channel-sections G are received by thechannels lb 72." in the outer corner-section, the channels Z1. it" beingof a width to permit lateral adjustment of the outer sections G forproviding final adjustment of the frame to size. An aperture Z17" givesclearance for the bolt and nut A spring I is suitably secured to one ofthe stiles when used as a window-screen, the rail also in that casebeing provided with lifts K.

For affording a ready means for inserting or removing the screen whenused as a window-screen and forming a runway of simple and durableconstruction I provide the runway L, comprising, preferably, anangle-plate Z of substantially the length of the runway and angle-platesZ and Z at the respective ends of the angle-plate Z, there being a spaceZ between the angle-plates Z and Z of a length slightly less than theheight of the screen. If the runway is of a length substantially theheight of the window-frame, as is usually the case for ordinarywindow-frames, the angleplate Z will be of a length slightly longer thanthe height of the screen, the angle-plate Z being short, with the spaceF of suflieient length to permit ready insertion of the screen-frameinto the channel Z of the runway, the front walls of the angle-plates ZZ taking over the top and bottom, respectively, of the screenframe. Informing the runway the angleplates Z Z are placed to rear of theangleplate Z, with nails m or other retaining means taking through slotsZ in the angle-plates and into the window-frame M for forming therunway, the slots being provided for permitting adjustability betweenthe walls of the runway.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is
